The Semi-continuous Tray Dryer

The Semi-continuous Tray Dryer

Semi-continuous cabinets were developed by Practical Action in order to overcome some of the disadvantages of the batch system. In a semi-continuous cabinet a lifting mechanism allows all of the trays except the bottom tray to be lifted.

Sand Dryer

All Tech Fabrication Machines sand dryers are designed around the specific process and material goals of the application at hand. Our sand dryers can process in excess of 300 TPH in a single unit and feature:

Diameter: 3′ – 15′ (1 – 4.6m)

• Co-current or counter-current air flow configuration
• FEECO combustion chamber
• Customizable flights/material lifters
• High-quality materials of construction to minimize sand abrasion
• Process and mechanical warranties
• Various drive assemblies available
•  Accommodates various fuel types

Silica sand Dryer

We offer our clients a fine and excellent grade Silica Sand Dryer, which is used in drying and cooling of materials that flow freely. This product is provided with a rotating shell which is supported on rollers & tires. Our product is available in various configurations. It requires a 7.5HP to 25 HP electric motor to work efficiently. The Silica Sand dryer we provide is very helpful in the various processes.

Working Principle

Firstly, use one belt conveyor or bucket elevator to Sand the wet silica sand into the drum of Silica Sand Dryer

• Conveyed from the feed screw directly into the Silica Sand Dryer, raised by the drum wall panels repeatedly, and scattered by the crushing blow devices.
• Materials and the negative high-temp media are combined sufficiently to complete the heat and mass transfer process.
•  The result of the drum wind angle and induced air, feed materials moving slowly and being discharged from the spiral after drying, exhaust gas handled by the cyclone, venting to the atmosphere.
•  The dryer adopts the riding wheel device, which makes the riding wheel and the rolling ring linear touch all the time. Thus the abrasive and the power loss are greatly reduced. The granularity and the moisture and be controlled by the customer’s demand. When drying the coal slurry, the product moisture can be less than 5% and the granularity and be less than 6mm.
